With the inputs I’ve gotten, I’ve decided to purchase today AA 5 to test in my j frames with 158 gr SWC. Decided against Unique and Power Pistol (PP) for the snubby (these two powders I like in longer barrels, 4 inches and up)...PP has too much blast and noise in the snub while I have to push the 158 gr at max Unique +P charge (5.2 grs, Speer data).
I’ve loaded 6.2 grs of AA5 with Speer 158 gr LSWC. Probably will get to the range next week to chronograph. I’m expecting approx. 775 FPS in the 1 7/8 barrel...we will see.
Appreciate your advice regarding AA5 in my application
